Claims

[Scope of utility model registration request]

A plurality of ink guide cores are arranged between a central core and ribs extending radially from the core to form ink capillary passages along the axial direction that communicate with each other via the tip edges of each rib. A bundle with an appropriate cross-sectional shape having a capillary guide path is surrounded by an outer sheath, and the brush tip of the bundle is sharpened, and an ink inlet is formed on the outer periphery of the rear part, excluding the sheath. A synthetic resin pen nib, which is formed by integrally fusing the rear end portions of each ink guide core in a converging body to each other.
